The park is wonderful, but it is very large, so it would be nice if they'd offer a tram service to get from one area of the park to another. They use trams for paid tours, so it can't be that hard to add trams to help visitors easily access all sections of the sprawling zoo. The biggest issue and the reason for 3 stars, is that they state that no "outside" food is allowed, but the food they offer is incredibly expensive and made poorly. We paid $5/soft pretzel and each was ice cold & soggy. $4 for a bottle of water.
